# Which Problems Are Solved
In the "new" structured logging, request details were added in different
middlewares, such as request, instance and user IDs. This meant the the
upstream request logging middleware did not have access to metadata that
got added later, resulting in incomplete logs. Furthermore it was not
possible to correlate an API error response to log output.
# How the Problems Are Solved
A mutable request details object is added to the context early on. When
the api authz function run, the instance and user IDs are added to this
object as they become available. Every logline emitted after this
(time-wise) will then all contain these details under the `request` log
group.

Request IDs are now also returned with a response header or metadata.
Depending on the protocol:
- HTTP calls always return the request ID as header, regardless of
status
- gRPC calls always return the request ID as header, even if there was
an error
- connect RPC calls returns the request ID as header on success, trailer
in case of error. This is because header must be set on the response
object, which is nil in case of error. When there is an error, metadata
can be added which are then sent as trailers.
# Additional Changes
- Use the existing call duration middleware for both request ID and
logging for a consistent request start timestamp in all layers.
- Upgrade sloggcp for some fixes (notably TraceID)
- Modify the NoCache middleware so it uses `SetHeaders` instead of
`SendHeaders`. The latter prevented any other handler from setting
headers, including the new request ID middleware.

# Which Problems Are Solved
While Zitadel provides a possibility to restrict certain languages to be
used, the corresponding list could not be retrieved in the settings
service (v2). This blocked login v2 implementations from respecting the
list and they would always use all available languages.
# How the Problems Are Solved
- Retrieve the list when checking the instance and pass it into the
context.
- Return it as part of the existing `GetGeneralSettingsResponse`
- This allows us to remove an additional query in some other cases /
endpoints.

# Which Problems Are Solved
Streams allow differentiating logs produced by different components of
Zitadel.
# How the Problems Are Solved
The `backend/v3/instrumentation/logging` package now exposes convenience
function for setting and getting a logger from the context. As well as
high-level functions to emit log records at various levels. When
constructing a new logger a "stream" needs to be specified:
- **runtime**: General runtime logs, such as startup and shutdown
messages. Default for logs that do not belong to the other categories.
- **request**: Logs for incoming API and HTTP requests.
- **event_handler**: Logs for event handling in projections.
- **queue**: Logs for the job queue processing.
- **event_pusher**: Logs for event pushing to the database. Disabled by
default, contains sensitive information.
Each line from the returned logger contains a `stream` field as well as
a `version` field with the current Zitadel version.
## Runtime config
Streams can be enabled by passing an array of stream names in the
runtime config. Because some log streams may contain sensitive data
(especially events), it is now also possible to mask values by their
key.
# Additional Changes
- Wrap `slogctx` in the `logging` package. (Except API error converter
packages, because of import cycle)
- Add some docs to `logging` package so other devs understand how to add
logging to Zitadel
- Add `logging.OnError` and `logging.WithError` helper functions with
`Panic()` and `Fatal()` methods, to preserve current calls in the `cmd`
packages.
- Add instance context extractor.
- Only output request details in the request info log. Request ID
remains propagated through context.
- Moved middleware functionality into protocol specific packages.
- Removed setting of URI to context in metric middleware. There were ony
setters and no getters. (Unused value)
- Reuse a single statusWriter in the middleware package for middlewares
that need to know the response status.

# Which Problems Are Solved
The following terms have all been renamed to management console:
- Customer Portal (when used to mean the console)
- Console
- Admin Console
# How the Problems Are Solved
- Search & Replace smartly
- Use Copilot for translation files
Changes done to: backend + frontend codebase, docs, translations and
protobufs (descriptions only)
# Additional Context
- Partially Closes#11279
# Which Problems Are Solved
The event execution system currently uses a projection handler that
subscribes to and processes all events for all instances. This creates a
high static cost because the system over-fetches event data, handling
many events that are not needed by most instances. This inefficiency is
also reflected in high "rows returned" metrics in the database.
# How the Problems Are Solved
Eliminate the use of a project handler. Instead, events for which
"execution targets" are defined, are directly pushed to the queue by the
eventstore. A Router is populated in the Instance object in the authz
middleware.
- By joining the execution targets to the instance, no additional
queries are needed anymore.
- As part of the instance object, execution targets are now cached as
well.
- Events are queued within the same transaction, giving transactional
guarantees on delivery.
- Uses the "insert many fast` variant of River. Multiple jobs are queued
in a single round-trip to the database.
- Fix compatibility with PostgreSQL 15
# Additional Changes
- The signing key was stored as plain-text in the river job payload in
the DB. This violated our [Secrets
Storage](https://zitadel.com/docs/concepts/architecture/secrets#secrets-storage)
principle. This change removed the field and only uses the encrypted
version of the signing key.
- Fixed the target ordering from descending to ascending.
- Some minor linter warnings on the use of `io.WriteString()`.

# Which Problems Are Solved
Zitadel encounters a migration error when setting `restricted languages`
and fails to start.
# How the Problems Are Solved
The problem is that there is a check that checks that at least one of
the restricted languages is the same as the `default language`, however,
in the `authz instance` (where the default language is pulled form) is
never set.
I've added code to set the `default language` in the `authz instance`

# Which Problems Are Solved
Milestones used existing events from a number of aggregates. OIDC
session is one of them. We noticed in load-tests that the reduction of
the oidc_session.added event into the milestone projection is a costly
business with payload based conditionals. A milestone is reached once,
but even then we remain subscribed to the OIDC events. This requires the
projections.current_states to be updated continuously.
# How the Problems Are Solved
The milestone creation is refactored to use dedicated events instead.
The command side decides when a milestone is reached and creates the
reached event once for each milestone when required.
# Additional Changes
In order to prevent reached milestones being created twice, a migration
script is provided. When the old `projections.milestones` table exist,
the state is read from there and `v2` milestone aggregate events are
created, with the original reached and pushed dates.
# Additional Context
- Closes https://github.com/zitadel/zitadel/issues/8800
# Which Problems Are Solved
The current v3alpha actions APIs don't exactly adhere to the [new
resources API
design](https://zitadel.com/docs/apis/v3#standard-resources).
# How the Problems Are Solved
- **Improved ID access**: The aggregate ID is added to the resource
details object, so accessing resource IDs and constructing proto
messages for resources is easier
- **Explicit Instances**: Optionally, the instance can be explicitly
given in each request
- **Pagination**: A default search limit and a max search limit are
added to the defaults.yaml. They apply to the new v3 APIs (currently
only actions). The search query defaults are changed to ascending by
creation date, because this makes the pagination results the most
deterministic. The creation date is also added to the object details.
The bug with updated creation dates is fixed for executions and targets.
- **Removed Sequences**: Removed Sequence from object details and
ProcessedSequence from search details
# Additional Changes
Object details IDs are checked in unit test only if an empty ID is
expected. Centralizing the details check also makes this internal object
more flexible for future evolutions.
# Additional Context
- Closes#8169
- Depends on https://github.com/zitadel/zitadel/pull/8225

# Which Problems Are Solved
ZITADEL currently selects the instance context based on a HTTP header
(see https://github.com/zitadel/zitadel/issues/8279#issue-2399959845 and
checks it against the list of instance domains. Let's call it instance
or API domain.
For any context based URL (e.g. OAuth, OIDC, SAML endpoints, links in
emails, ...) the requested domain (instance domain) will be used. Let's
call it the public domain.
In cases of proxied setups, all exposed domains (public domains) require
the domain to be managed as instance domain.
This can either be done using the "ExternalDomain" in the runtime config
or via system API, which requires a validation through CustomerPortal on
zitadel.cloud.
# How the Problems Are Solved
- Two new headers / header list are added:
- `InstanceHostHeaders`: an ordered list (first sent wins), which will
be used to match the instance.
(For backward compatibility: the `HTTP1HostHeader`, `HTTP2HostHeader`
and `forwarded`, `x-forwarded-for`, `x-forwarded-host` are checked
afterwards as well)
- `PublicHostHeaders`: an ordered list (first sent wins), which will be
used as public host / domain. This will be checked against a list of
trusted domains on the instance.
- The middleware intercepts all requests to the API and passes a
`DomainCtx` object with the hosts and protocol into the context
(previously only a computed `origin` was passed)
- HTTP / GRPC server do not longer try to match the headers to instances
themself, but use the passed `http.DomainContext` in their interceptors.
- The `RequestedHost` and `RequestedDomain` from authz.Instance are
removed in favor of the `http.DomainContext`
- When authenticating to or signing out from Console UI, the current
`http.DomainContext(ctx).Origin` (already checked by instance
interceptor for validity) is used to compute and dynamically add a
`redirect_uri` and `post_logout_redirect_uri`.
- Gateway passes all configured host headers (previously only did
`x-zitadel-*`)
- Admin API allows to manage trusted domain
